LIGHTING UNIT.

Application filed August 19, 1920.

To all ir/iom may con cern Be it known that IRMA); linnin, a citizen of the United States,residing at New York, in the county of New York and State oi New York, have invented a certain new and useful i'm 'irovement in Lighting Units, of which the following is a specification.

My invention relates to that class of. lighting fixtures known as semi-indirect units and which are generally constructed entirely of glass. Devices of this kind with which I am familiar are usually ol'ijectionahle. due to the fact that there is so much breakage, as they are necessarily of comparatively thin. glass. A slight accidental blow at the periphery of the reflector serves to break the globe and render the entire device useless, inasmuch as it is made of a single piece of glass. Furthermore, this type of unit is generally suspended by a lip :lormed at the center part of the reflector and in larger sizes, this support is not always eliicient.

My invention has for its object to provide a construction which will not only entirely obviate the possibility of breakage when the unit is accidentally struck, but also to provide an additional support. Other objects will appear in the hereinafter contained claims and description.

My means o1. accomplishing the loregoing objects may be more readily understood by having reference to the ac-courpanying drawings which are hereunto annexed and are a part of this specification, in which- The figure is a side elevation of a lighting unit constructed in accordance with my improvement, a portion of the exterior being broken away to show the interior construction.

Similar reference numerals refer to simi lar parts throughout the entire description.

As shown in the drawing, the unit is suspended by means of a chain 1, of the usual construction, to the lower end of which is secured a ranopy 2 which is provided with internal threads 3 at its upper end, which are titted to and engaged by the threads #1 on the end of a nipple 5. A socket 6 of the usual standard construction, is secured to the lower end of the nipple 5 and has an electric lamp bulb 7 mounted thereon.

A. holder 8 is secured to the nipple and is provided with a plurality of thumb screws 9 which engage the lip of the globe 11, This Serial No. 4,0 2,623.

globe is constructed of a single piece of glass and comprises an. upper portion 12, an inwardly tapering; conoidal portion 13 and a bowl shaped portion 14. Preferably, the conoidal portion 13 is formed of transparent glass, while the reflecting portion 1.2 and the bowl portion 14 are formed of translucent glass.

I provide an annular member 15, which is formed with an internal shoulder 16, upon which rests the periphery of the reflecting member 12, thus serving to relieve the strain on the thumb screws 9 and lip 11*" of the globe 11, at the same time, the annular member effectually prevents the class being accidentally struck and broken. The annular member 15 may be supported by means of arms 17 which extend outwardly from the holocr 8 or they may be secured adjacent the edge of the canopy 2. A ventilating; pcning 18 is provided in the lower part of the bowl 14 and an ornament 19 may be mounted therein, as shown, a tassel is employed for this purpose.

Although I have shown and described my improvement as an annular member it may be found desirable in practice to make it of .a different form, and I do not desire to be limited to the specific construction shown except as such limitations which appear in the hereafter appended claims.

it will be obvious to persons skilled in the art, that a lighting unit constructed in this manner, provides a highly etiicient fixture, for the light rays emitted by the electric lamp bulb 7 which do not pass directly through the bowl 14,- will be directed upwards, striking the reflecting portion 12, whence they will be directed downwardly through the transparent or conoidal portion 13.

At the same time, when the reflecting portion 12 is made of translucent glass, a sul'licient amount oi. light will pass therethrough to be softly diffused, thus preventing); any shadows from being *ast on the ceiling.

It will also be apparent that the danger of breal zage is almost completely obviated, and practice has shown that this breakage is a serious feature in lighting units employing this type of globe.

Having described my invention what I regard as new and desire to secure by Letters Patent is:

ported thereby, a nipple secured within said canopy, a socket and bulb secured to said nipple, a globe holder mounted on said nipple and Within said canopy, a one-piece bowl having its upper edge engaged and closed by the canopy, means on said holder to support the middle portion of said globe, arms extending from the globe holder at the point of junction of the canopy and globe and being secured to the supporting and protecting annular member.

In Witness whereof I have signed the foregoing specification.

MAX KLEIN.
